Hello, the picture in the attachment is an example of a template that I think is more in line with the mythological background. Is the PPT system for MAC iOS or Windows?

For Mac, you can add an ink parchment theme, which is antique.

In fact, customized themes are more in line with mythological topics. You can choose "Science Fiction. Myth. Greek Mythology" and other simple composition background desktop images from search engines such as Baidu, Yahoo, and Nitu, and drag them directly into PPT or set them as the background.

.

It is recommended to default to clearer fonts such as boldface or italics. If you add unclear coverage, you can add a translucent color frame to the text. You can find text boxes of different colors in the "Format" column.

Advanced production can add animation and page transition effects, but it is more troublesome.

I hope you will adopt the above, thank you.
